Simplifying (2x−6y8)(−5x5y−3)(2x^{-6}y^8)(-5x^5y^{-3}) and (3u−5v7)(−4u4v−2)(3u^{-5}v^7)(-4u^4v^{-2}) Using the Product Property

Simplify products that involve both numerical coefficients and multiple variables with negative exponents by grouping similar components.

ⓐ (2x−6y8)(−5x5y−3)(2x^{-6}y^8)(-5x^5y^{-3}): Rewrite the expression by grouping the numerical coefficients and the like variable bases together: 2(−5)⋅(x−6x5)⋅(y8y−3)2(-5) \cdot (x^{-6}x^5) \cdot (y^8y^{-3}). Multiply the coefficients (2(−5)=−102(-5) = -10) and add the exponents for each variable base: for xx, −6+5=−1-6 + 5 = -1; for yy, 8+(−3)=58 + (-3) = 5. This yields −10x−1y5-10x^{-1}y^5. Finally, use the negative exponent definition to move only the factor with the negative exponent (x−1x^{-1}) to the denominator: −10y5x\frac{-10y^5}{x}.

ⓑ (3u−5v7)(−4u4v−2)(3u^{-5}v^7)(-4u^4v^{-2}): Group similar components: 3(−4)⋅(u−5u4)⋅(v7v−2)3(-4) \cdot (u^{-5}u^4) \cdot (v^7v^{-2}). Multiply the coefficients to get −12-12. Add the exponents for uu (−5+4=−1-5 + 4 = -1) and for vv (7+(−2)=57 + (-2) = 5), resulting in −12u−1v5-12u^{-1}v^5. Apply the negative exponent definition to rewrite u−1u^{-1} in the denominator, giving −12v5u\frac{-12v^5}{u}.

Numerical coefficients are multiplied normally. Only variables that end up with negative exponents are relocated to the denominator.
